Change I3358109b1c6997961c1cb73e114dd938fb9ff1e2 (in hibiscus, not yet released) added cross-pool clone support for NetApp iscsi/fc and made the driver report clone_across_pools: True.  But apparently it doesn\u0027t work well, so this patch has the driver report clone_across_pools: False.  There is another change I4941197a2df741f80c317fb9e270f29f6fb085b2 (in the cinder main code, not driver code) currently under review that introduces an option to control whether drivers who report they can clone_across_pools will actually do it.  Is there a patch that turns clone_across_pools on for any netapp drivers?\n\nI\u0027m asking because I share Rajat\u0027s concerns about the release note.  See comments inline.\n\nI\u0027m also unclear on what exactly the change in client_cmode.py is for.  It seems to be fixing some kind of bug, but it\u0027s not clear from the commit message what exactly the issue is.","commit_id":"a9bf30f7b6293b3113af7141aeabeca42da8ade4"},{"author":{"_account_id":27615,"name":"Rajat Dhasmana","email":"rajatdhasmana@gmail.com","username":"whoami-rajat"},"change_message_id":"5f6c456e18552df6ed8d0a6ce6d92c528f7dd9ed","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":4,"id":"a086aa3b_8f1140e5","updated":"2026-09-03 11:52:24.000000000","message":"I\u0027ve concerns noted inline, i still feel [1] is more straightforward i.e. to not pass vserver details in case of clone across pools.\n\n[1] https://review.opendev.org/c/openstack/cinder/+/1003076","commit_id":"a9bf30f7b6293b3113af7141aeabeca42da8ade4"},{"author":{"_account_id":36171,"name":"jayaanand borra","display_name":"jayaanand borra","email":"jayaanand.borra@netapp.com","username":"jayaanan","status":"netapp"},"change_message_id":"c49b31261afb82df4d9256c7b7c52b89c233c3d8","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":4,"id":"6ec84c04_4a4a179e","updated":"2026-09-03 07:44:29.000000000","message":"we will enable cross-pool cache capability as part of V2 release","commit_id":"a9bf30f7b6293b3113af7141aeabeca42da8ade4"}],"cinder/volume/drivers/netapp/dataontap/block_cmode.py":[{"author":{"_account_id":27615,"name":"Rajat Dhasmana","email":"rajatdhasmana@gmail.com","username":"whoami-rajat"},"change_message_id":"5f6c456e18552df6ed8d0a6ce6d92c528f7dd9ed","unresolved":true,"context_lines":[{"line_number":679,"context_line":"        # Used for service state report"},{"line_number":680,"context_line":"        data[\u0027replication_enabled\u0027] \u003d self.replication_enabled"},{"line_number":681,"context_line":""},{"line_number":682,"context_line":"        data[\u0027clone_across_pools\u0027] \u003d False"},{"line_number":683,"context_line":""},{"line_number":684,"context_line":"        # Surface disaggregated\\-platform flag at the backend level"},{"line_number":685,"context_line":"        data[\u0027netapp_disaggregated_platform\u0027] \u003d ("}],"source_content_type":"text/x-python","patch_set":4,"id":"163a9292_ff00d1d2","line":682,"range":{"start_line":682,"start_character":8,"end_line":682,"end_character":42},"updated":"2026-09-03 11:52:24.000000000","message":"why are we disabling it here? this will cause the optimized path to never get triggered, am i missing something?","commit_id":"a9bf30f7b6293b3113af7141aeabeca42da8ade4"},{"author":{"_account_id":38059,"name":"Anoop Kumar Shukla","display_name":"Anoop Shukla","email":"anoop.shukla@netapp.com","username":"anoop2","status":"NetApp"},"change_message_id":"4e56557239d5dfaf047dd8b1e5cb1458c854a8de","unresolved":true,"context_lines":[{"line_number":679,"context_line":"        # Used for service state report"},{"line_number":680,"context_line":"        data[\u0027replication_enabled\u0027] \u003d self.replication_enabled"},{"line_number":681,"context_line":""},{"line_number":682,"context_line":"        data[\u0027clone_across_pools\u0027] \u003d False"},{"line_number":683,"context_line":""},{"line_number":684,"context_line":"        # Surface disaggregated\\-platform flag at the backend level"},{"line_number":685,"context_line":"        data[\u0027netapp_disaggregated_platform\u0027] \u003d ("}],"source_content_type":"text/x-python","patch_set":4,"id":"8f223f33_18abb54b","line":682,"range":{"start_line":682,"start_character":8,"end_line":682,"end_character":42},"in_reply_to":"029526e2_6d7b6037","updated":"2026-09-03 14:16:33.000000000","message":"Customers are used to warm the pool with cache manually before creating the VMs. Forcing them to go to copy path for all the VM creations, ends up taking time for bulk volume provisioning.
